V'Application filed May 20,

To azZZ whom t may concern:

Be it known that I, Grenen 1V. VVnscI-in, a citizen of the UnitedStates, residing at VVellsville, in the county of Allegany `and State ofNew York,'have invented certain new and useful `Improvements inHydrocarbon Burners, of which the following isa specification. Y j

This invention relates to an improved hy drocarbon burner and seeks,among other objects, to provide a simple and yet highly efficient burnerwhich, from a given quantity of fuel, will produce more heat than otherburners of like character as now offered on the market v The inventionseeks, as a further object, to provide a burner which will benoiseless,` odorless, and free from' carbon deposits.

And the invention seeks, as a still further object, to provide a burnerwhich may be readily assembled or disassembled and thus readily capableof repair, and which ,will bo adapted for general use.

Other and incidental,objects will appear hereinafter. f

In the drawings:V

Figure 1 is a plan view of my improved burner, y

Figure 2 is a vertical sectional viewV on the line 2-2 of Figure 1,looking in the direction of the arrows,

Figure 3 is a detail sectional viewon the line 3-8 of Figure 2, t f

Figure 4 is a detail sectional view on the line le-4: of Figure2,-looking in the rdirec-V tion indicated by the arrows, and v 'Y Figure5`v is a sectional view on the line 55 of Figure 1, looking in the,direction indicated by thevarrows. i

In carrying the invention into effect, I employ a vstand 1() onwhich isintegrally formed a circular burnery bowl 11 and risinof from the standat one end thereof'is .an

iniierted U-shaped bracket which is also preferably integral with thestand lso that i the stand, bowl and `bracket thus" comprise a singleunit. Mounted upon'the bracket V12r is an oblong headerblock 13 recessednear its ends to freely receivefstuds 13 upstandf ing fromthebracket'andmounted upon the bracket to extend freely through the blockcentrally thereof is a rod 13b carrying a thumb nut 1.3' detachably'securingfthe block in ositicn.

thereabove.- Near its ends, the block 13 isl provided with transversepassages 15 and 16 therethrough and formed on the block at the forwardends of said passages are nipples 17. Detachably connected at its endsto said nipples is a horseshoe-shaped generator tube 18y attached to thenipples by nuts 19 and extending from end to en d of the tube is anasbestos or other suitable fibrous member 20, for collecting carbondeposited by the liquid fuel when the burner is operserved,the'generator tube is centered with respect tothe bowl 11 and extendshorizone tally thereabove in parallel relation to the bowl. Mounted uponthe block 13 at Vthe passage 16fis an injector nozzle 21 which,

As will be obas shown in Figure 2, is composed of companion sections oneof which is formed with a nipple 22 screwed into said passage while theother of the sections is provided with an alined outlet orifice 28. Thesections of the y nozzle are detachablyconnected by rods or othersuitable fastening elements 211 and clamped between said sections isalami nated asbestos gasket 25 between the laminations of which is heldan atomizing screen 26. Secured to the screen centrally of the openingthrough the gasket is a circular asbestes baiiie 26 centered withrespect to Ythe nipple 22. Thus, fuel vapors `issuing from the `nipplewill strike the bafiieto be spread .out into a circular sheettherebywhen the f Vvapors will pass over the edge of the baffle and. throughthe screen 26 to be atomized by the screen. Any liquid particles in thefuel vapors will accordingly be broken upwhile the vapors `will bepreventedfrom iinpinging directly against vthe screen to force liquidparticles therethrough.`

Mounted upon the bottom wall of the bowl i 11 is an induction tube 27gradually tapered in diameter from` one end thereof to the other'. Atits larger end, the wall Vof the tube is-thickened and formed on thetube is an annular flange 28 bolted or otherwise securedto said bottomwall .axially of the bowl.r The smaller end portion of the tube isarranged to extend upwardly and `forwardly to confront the block 13 andformed on the tube at its smaller end is a depending p nozzle 21 vtorest thereon abutting the block. As brought out in Figure 2, the hood isopen at its forward sideneXt to the burner bowl and is also open at itslower end. Detachably mounted axially of the bowl ll is a tubular burnerhead 30 provided at its lower end with a reduced nipple 3l extendingfreely through a suitable opening in the. bottom wall of the bowl ll andscrewed into the adjacent end of the tube losing the head at its upperend is a removable cover plate 3:? and clamped between the head and thebottom wall of the bowl is an appropriate wick 35 of asbestos or thelike. Screwed at their inner ends into the head is an upper and lowerseries of radial burner tubes 3l closelyY approaching the side wall ofthe bow.1 and, as will be observed, the tubes of one series arestaggered with respect to the other so that the several tubes areequally spaced circumfereutially of the head.

ln the present instance, I have provided al base for th-e stand l0 byemploying a casing- 3:3 to which the stand is detachably secured, andremovably fitting in the casing` is a fuel supply tank 3G provided atone end with a. filler pipe 3T. Leading from the tank is afuel feed pipe38 and formed on the outer si-del ofthe block 13 at the adjacent end ofthe passage is a nipple 39 to which the pipe is detachably connected bya nut Interposed in the pipe adjacent the tank is a suitable shut-ottvalve #ll and projecting from the adjacent end wall of the tank is anappropriate airvalve to which a suitable pump may be attached forforcing air into the tank so that the fuel contained by the tank may bedelivered through the pipe 3S by air pressure. However, if preferred,the tank may be mounted at a suitaliile elevation above the burner sothat the liquid fuel will gravitate to the burner.

The burner is started b v saturating the wick S3 and ignitiug the fuelin the howl so that the generator tube 18 will be heated. rllhe valveLll is then opened, when the fuel will flow into said generator tube.The fuel will thus be vaporized in sai-d tube and the fuel vaporssuperheated to form a fuel gas, which gas will issue into the nozzle 2lto flow through the screen Q5 and filter member 26, when the gas willissue through the oritice 23 of the nozzle into the adjacent end of theinduction tube 2T. Air will accordingly be. drawn in through the hood 29to flow through the tube along with the fuel gas so that the air and gaswill become comi'ningled to produce a highly combustible fuel mixturewhich will issue through the burner tubes to be ignited at the outerends thereof. rlhe flame thus produced will be confined and directed bythe bowl to rise upwardly about the generator tube i8 so that as soon asthe burner is in operation this tube will be highly heated. Acorresponding effective vaporization of the liquid fuel and superheatingof the fuel gas will thus be realized with the result that practicallyperfeet combustion of the final fuel mixture will be had. Accordingly,an intensely hot flame will be produced while, at the same time, carbondeposits will be minimized. Since the head 29 of the tube 2 is open atthe side thereof next to the bowl, the air drawn into the hood will beheated while the heat radiating from the bowl will serve to appreciablyheat the hood as well as the injector nozzle 2st. Furthermore, it is tohe noted that since the induction tubel 27 is gradually increased indiameter toward the discharge end of the tube, the fuel gas will, as itflows through the tube, be allowed to expand somewhat and accordinglytak-e up the heat from the metal of the tube while the flow of gas andair through the tube will be accelerated to overcome possible backtiring.
